A comparative performance study of scalar controlled induction motor using PID controller and fuzzy PID controller

Conventional PID controllers have been extensively used for the control of induction motor drives in industries. But the performance of these controllers are greatly affected by parameter variation and modelling uncertainties. Also these type of controllers have stability issues. But on the other hand fuzzy logic based PID controllers are robust fast and accurate. In this paper the performance of a scalar V/F controlled induction motor drive is evaluated using conventional PID controller and fuzzy PID controller and the results are compared. The whole modelling and simulation work is done using Matlab/Simulink environment.
